We custom design and manufacture

Superconducting and Dielectric Bandpass Filters for the Frequency Range from 800 to 2000 MHz

Our CryoSelect® HTS bandpass filters surpass by far the conventional metallic cavity filters predominantly used in todays wireless communication base stations. They are also superior in their characteristics to modern dielectric filters. It is expected that they will extend coverage and/or capacity of wireless base stations
